after my truck warms up it will die when i stop it will start right back on 1994 Ford Ranger

when driving down the road it feels like you have let off of the gas for a few seconds then it kicks back in. i have to give it a lot of gas to take off from a dead stop after driving it for a while. it is also running a little warm. i have replaced fuel pump, filter, regulator, fuel relay, water pump, thermostat, plugs and wires and had the exhaust replaced. what could be causing all of these problems?
